in your near future or you don't mind buying another ice axe, go with the camp corsa. it's perfect in the roll of extra insurance when sticking to snow fields. if i was planning on any real glacier travel or was going to be pounding in pickets, i'd avoid the corsa with its aluminum head. another light axe that comes in around 14 oz is the grivel air tech race. i've seen it on sale recently for around $125. not sure how that compares to the prices you've seen on the corsa or raven pro.

length is a real personal issue. if not too steep terrain a 60 cm or thereabouts is fine.

Which one has more pick/adze/spike length on it? IE which one can be sharpened more than the other? Are you 95% backpacking and just want to get across steep snow slopes that may have a gory end at their bottom? Then whichever is lighter. If more into summiting peaks, go with the axe that has more life time wear length to it.

Sorry, don't have each embedded into my mind as to which is what. My backpacking axe is about ready to be thrown out as I have sharpened it too many times. Lasted me about 10 years of backpacking/scrambling. Most often used to dig "cat holes" and dry tooling up summits that I really should have had a rope for... Or self belaying down super steep mud/heather etc. Ice climbing axes are a whole'nother kettle of fish and unless you are into vertical ice are a waste of money IMO.

A sharp axe makes a gigantic difference on semi technical routes. Same with sharp crampons.

Thanks for the info, all. And thanks for the link, Paul. Must have missed that one.

I don't anticipate carrying an axe very often, or for many days, but my base weight is plenty light enough to allow a few extra ounces. At this point, I'm tilting toward the BD Raven Pro for wider range of use, increased durability, and (slightly) lower price. Plus, a local independent shop carries them, and I like giving the guy my business when I can.

The Corsa is aluminum, making it useful only for occasional snow travel during the summer.

The Raven Pro is a lightweight axe, in the style of a typical mountaineer's tool, sufficient for all conditions of snow/ice/glacier.

With that said though, the Raven has a better pick for self-arrest. IMO, the Raven Pro isn't as good a mountaineering axe as the Raven.

Length is, to a degree, a personal thing. The standard these days is easy enough to measure. Pick up and axe, and gently hold the head in one hand, letting the spike end droop near the ground. With your arms comfortable relaxed at your side, the tip of the spike should come to your ankle. For gentler walk-ups and hiking-oriented travel, a bit longer length is recommended.

The Corsa is a very limited tool. I have one for backcountry ski trips. You wouldn't want to do anything but self-arrest with it (or just use it on an uphill or traverse where you're plunging the shaft into the snow as a handhold). It's so light that it's almost useless for cutting a step. A little more weight in the head is very useful if you want to do anything besides self arrest.
